Important update to the Elektor
500 ppm LCR Meter

Since this project was published in three installments several hundred of the instrument have been built, to the great satisfaction of their users, the author, and Elektor editors alike. The author has now corrected two shortcomings liable to interfere with proper operation under certain conditions.The two points worthy of attention are the fact that the instrument seems to ‘hang up’ when measuring low resistances (<1 Ohm); and the apparent impossibility to perform Trim actions.
